How do I find out the architecture of processor commands in linux?
The question arose, which package to install: http://www.rpmfind.net/linux/rpm2html/search.php?query=qemu-sgabios+noarch.rpm&submit=Search+...&system=&arch=
In /proc/cpuinfo and lscpu, only the architecture of the processor itself is shown. I am not an ironworker, please do not throw stones.

Architecture: x86_64
What's wrong with that? The CPU architecture you have is amd64, aka x86_64.
In general, packages of different architectures can be installed on the system.
If the rpm package system is the main one, then you should focus on which architecture most of the installed packages are built for. example:
$ rpm -qa --qf "%{arch}\n" | sort | uniq -c
91 i386
2 i686
68 noarch
4 (none)
464 x86_64
It can be seen that the most packages (464) are for the x86_64 architecture. it is the main one.
For the system deb - the main one is a little easier. there is a basic architecture. example:
$ dpkg --print-architecture
amd64
And (may be) "third-party" architectures. example:
$ dpkg --print-foreign-architectures
i386
For distributions that are not based on rpm and not on deb, I can't immediately suggest anything. I hope that in the comments my answer will be supplemented by specialists in such distributions.
There is probably a universal solution: ask glibc how the basics of the gnu/linux operating system work.
For a 32-bit build glibc, the answer is 32:
$ getconf LONG_BIT
32
For 64-bit - 64:
$ getconf LONG_BIT
64
There are several variants of the names of this technology, which sometimes lead to confusion.
X86-64-initial version. It was under this name that the first preliminary specification was published by AMD.
X64 is the official name of the versions of the Windows and Solaris operating systems, also used as the name of the architecture by Microsoft and Oracle.
AA-64 (AMD Architecture 64) - so the architecture was named by a popular unofficial reference sandpile.org (entering the information almost immediately after the publication of the first preliminary specification) by analogy with IA-64. Hammer Architecture-the name of the first processor cores that supported it-AMD Clawhammer (nailer) and AMD Sledgehammer (sledgehammer).
AMD64 - after the release of the first Clawhammer and Sledgehammer, the name of the AMD developer company appeared in the architecture name. It is now official for the AMD implementation. Yamhill Technology - the first name of the implementation technologies by Intel. Sometimes the name CT (Clackamas Technology) was mentioned.
EM64T is the first official name of the Intel implementation. It stood for Extended Memory 64 Technology. IA-32e-sometimes used in conjunction with EM64T, more often to refer to the long mode, which in Intel documentation is called "IA-32e mode".
Intel 64 is the current official name of the Intel architecture. Intel is gradually abandoning the names IA-32, IA-32e and EM64T in favor of this the name, which is now the only official name for this architecture from Intel.
